In a beam-dump experiment at Fermilab the cross section for charm-particle production has been deduced from a measurement of the prompt neutrino flux. The reaction cross section, if we assume only DD-bar and the dependence on atomic weight A/sup 0.75/, is 57.2 +- 2.9 +- 8.5 ..mu..b/nucleon and the dependence on Feynman x and transverse momentum is E/sub D/ d/sup 3/sigma/sub pD//sup 3/proportional(1-x)/sup 3.2/e/sup -1/ .5p/sub perpendicular/ (p/sub perpendicular/ in GeV/c). The data are consistent with as much as 40% diffractive production of ..lambda../sub c/D-bar.
